Want to know if Cas9 is active in your cells? Cellecta’s CRISPRtest™ method allows you to assess the level of Cas9 activity in your cell line using two pre-mixed lentiviral-packaged vectors, the first containing a green fluorescent protein (GFP) marker and gRNA sequence targeting an essential gene (PCNA), and the second containing a red fluorescent protein (RFP) marker and a non-targeting gRNA. Transduction of CRISPRtest virus into cells will result in a mixture of cells expressing ... Read more

Want to know if Cas9 is active in your cells? Cellecta’s CRISPRtest™ method allows you to assess the level of Cas9 activity in your cell line using two pre-mixed lentiviral-packaged vectors,

  • the first containing a green fluorescent protein (GFP) marker and gRNA sequence targeting an essential gene (PCNA), and
  • the second containing a red fluorescent protein (RFP) marker and a non-targeting gRNA.

Transduction of CRISPRtest virus into cells will result in a mixture of cells expressing GFP and cells expressing RFP. Upon cell growth in the presence of active Cas9, the ratio of GFP cells: RFP cells will decrease proportionally to Cas9 activity.

The CRISPRtest Functional Cas9 Activity Kit, currently for human cell lines only, is an easy-to-use, highly sensitive kit for measuring functional Cas9 activity in almost any human cell line.
